    Miss Estruch I wanted you to know the impact your videos have had on me. I got a 9 in Biology at GCSE, I loved it so much. But I struggle with ASD, chronic fatigue, and anxiety, which made going to school really hard for me. I attended school for some of year 12, but at the end of year 12 I experienced a huge trauma that left me unable to attend school at all. I tried to attend again in year 13, but unfortunately I had missed so much work and my biology teacher did nothing to help me catch up, I emailed her everyday asking her for work to do, she never responded to a single email and I ended up missing almost the whole of Year 13. Both my Mum and I emailed so many times asking for a meeting, or for work to be sent home so that I could pass Biology at least, but she completely abandoned me. I sat my paper 1 last week, after not hearing from my biology teacher in months, and it went so well, thanks to your videos. I'm now using your videos to learn paper 2 content, and I'm so grateful to have this resource, it's the difference between me failing and passing. I'm really glad that you actually teach the content, rather than just skimming over it as a revision guide. The time that you have put into your videos is the reason why so many students will be able to overcome all the barriers stopping them, and achieve great results that they can be proud of. Thank you so much.

Come year 12, I’m hospitalised for almost the entire year and no matter how much I catch up I always feel behind everyone else, and I have no motivation to do anything. Have my paper 2 mock tomorrow, I know I’m not going to do great but I’ll try my best. I hope your life is going better now 💜

      no ur not, watch this video 2 times on 2x speed (or use a chrome extension to make it faster) and then as u go through it write anything ur likely to forget e.g. the word chemiosmosis, and then u have a sheet to go through. lastly do an exam paper, but after u answer each question look at the mark scheme (or a walkthrough) sm stuff has set answers e.g. to increase absorption u always say microvilli and more carrier/channel proteins. you got this. reply if u have any questions. there is still a few days.
      also i recommend depending on ur brain, imagining everything, like actually visualize respiration, or a bug chilling under a log in its niche, this helps me remember stuff without the need for heavy memorization, hence why chem is where i am burnt beyond consumption
      pioneer species result in a thin layer of humus or humus the food as i chose to remember it by
      also watch 10 minutes, then blurt, then another 10, and so on. then when u get to like 40 minutes blurt all.

    just me being pedantic, but 1:23:10 slow and fast twitch fibres dont actually have designated locations in the body, they are just present in different proportions in the body depending on adaptations. for example, a 100m sprinter will have a high proportion of fast twitch fibres throughout their body due to the explosive nature of their sport, compared to a marathon runner who will have a high proportion of slow twitch fibres due to the endurance aspect of their sport. this probably isnt on the spec, but just useful to know :)

    kidneys content is not close to how much is required by the specification at all.
    no mentions of arterioles, glomerular filtrates, etc.

    • @mariahasan1350
      @mariahasan1350 Рік тому

      You dont need to know the ins and outs of HOW it makes them more permeable - just that more ADH makes the DCT and collecting duct more permeable so more water can be reabsorbed back into the body if water potential is too low resulting in more concentrated urine

    I thought the H+ ions are actively transported out of the thylakoid into the thylakoid space, not the stroma, then via the ATP synthase back into the thylakoid not the stroma?

    • @ta647
      @ta647 Рік тому +3

      protons are actively transported across the thylakoid membrane into the thylakoid space from the stroma.​ The pumping of electrons via the electron transport chain and those produced by photolysis establishes an electrochemical gradient - higher concentration of protons in the thylakoid space than stroma.​
      ​Protons then diffuse (facilitated) through ATP synthase. The shape of ATP synthase changes as protons move through which releases energy causing ADP + Pi to form ATP. ​
